[PATCH 0/2] Allow drivers to tap into tags initialization

[Matias Bjorling]

These two patches enable a driver to control if tags should be initialized or
use an existing tags structure.

This is for example needed for the NVMe driver, that have a shared number of
queues for each block device it expose.

Matias Bjorling (2):
  blk-mq: allow request queues to share tags map
  blk-mq: add maps_tags fn and add usage
